31 State-of-the-Art Landfills

32 State-of-the-Art Landfills

33 State-of-the-Art Landfills

34 State-of-the-Art Landfills So landfills were designed and constructed to protect groundwater as well as stormwater. But things change Especially solid waste regulations

44 Primary On-going Issues with Stormwater Management

45 Four Primary On-going Issues with Stormwater Management 1. Areas outside of landfill were never designed for adequate stormwater management

46 Four Primary On-going Issues with Stormwater Management 1. Areas outside of landfill were never designed for adequate stormwater management 2. Best Management Practices (BMPs) are not adequately maintained

47 Four Primary On-going Issues with Stormwater Management 1. Areas outside of landfill were never designed for adequate stormwater management 2. Best Management Practices (BMPs) are not adequately maintained 3. Operators don t review their Stormwater Pollution Prevention Plan (SWPPP)

48 Four Primary On-going Issues with Stormwater Management 1. Areas outside of landfill were never designed for adequate stormwater management 2. Best Management Practices (BMPs) are not adequately maintained 3. Operators don t review their Stormwater Pollution Prevention Plan (SWPPP) 4. Operators don t communicate issues with their management, their consultant, or the MPCA

49 Issue #1: Stormwater Management

50 Issue #1: Stormwater Management Outside of Landfill

51 Issue #1: Stormwater Management Outside of Landfill

52 Issue #1: Stormwater Management Outside of Landfill

53 Issue #1: Stormwater Management Outside of Landfill

54 Issue #1: Stormwater Management Using Existing Features

55 Issue #2: BMP Maintenance Erosion and sediment build-up

56 Issue #2: BMP Maintenance Record snowfalls bring record runoff

57 Issue #2: BMP Maintenance Flooding can occur

58 Issue #2: BMP Maintenance Water will drain downhill

59 Issue #2: BMP Maintenance Erosion will occur

60 Issue #2: BMP Maintenance Litter will blow

61 Issue #2: BMP Maintenance Vegetation won t grow

62 Issue #2: BMP Maintenance Dirt and mud will build up

63 Issue #2: BMP Maintenance If you can t keep up with your BMP maintenance or you feel your maintenance must occur too frequently, the design or construction may not adequate.

64 Issue #2: Good Housekeeping

65 Issue #2: Good Housekeeping

66 Refresher: Industrial Stormwater Program Goal is to reduce the amount of pollution that enters surface and ground water from industrial facilities in the form of stormwater runoff. This goal is accomplished by requiring permitted facilities to: Develop an effective Stormwater Pollution Prevention Plan (SWPPP) which contains your Stormwater Control Measures, described as Best Management Practices (BMPs). Manage stormwater runoff by meeting the permit requirements

67 Issue #3: Stormwater Pollution Prevention Plan Updated annually Training required annually How often should you review your SWPPP? Review SWPPP to be able to answer what, where, and why regarding: Pollutant Sources Spill Prevention and Response (SPCC Plan) Good Housekeeping Best Management Practices (BMPs)

68 Issues #3 and #4: SWPPP and Communication The Landfill Operator becomes the most knowledgeable and the best critic regarding the adequacy of the SWPPP and the conditions of the Industrial Stormwater Permit Nobody knows your site like YOU do

69 Issues #3 and #4: SWPPP and Communication Can you answer these questions about your facility?

70 Issues #3 and #4: SWPPP and Communication What do you do if...

71 Issues #3 and #4: SWPPP and Communication If you find drainage isn t adequate

72 Issues #3 and #4: SWPPP and Communication If you experience a failure of a BMP

73 Issues #3 and #4: SWPPP and Communication If a leak or a spill occurs on-site

74 Issues #3 and #4: SWPPP and Communication If a leak or spill occurs to Waters of the State

75 Issues #3 and #4: SWPPP and Communication If you can t collect a sample

76 Issues #3 and #4: SWPPP and Communication If you forget to collect a sample or forget to submit a report

77 Issues #3 and #4: SWPPP and Communication If you are planning construction or if you have modified site conditions that changes drainage, impervious surfaces, or discharge locations

78 Issues #3 and #4: SWPPP and Communication If your sampling results exceed benchmarks

79 Number One Recommendation for Stormwater Management Never stop improving site conditions and operations It is expensive to do all at once, but no one knows what is working and what isn t working better than you.

87 Best Management Practices

88 Best Management Practices

89 Reminder: Additional Permit Requirements Operations not meeting specific terms and conditions of the permit will be in violation of State and Federal regulations. MPCA is authorized to enter and inspect the facility. SWPPP must be kept on-site at all times and made available to agency inspectors. Any inspections or BMP changes must be documented.

90 Conclusions: Get to know your SWPPP The Landfill Operator becomes the most knowledgeable and the best critic regarding the adequacy of the SWPPP and the conditions of the Industrial Stormwater Permit Nobody knows your site like YOU do
